Anyone else hoping that, with the new availability of sandy bridge from intel, that Apple with refresh the mbp with said line? That would mean a 22% shrink in real estate, thus, they might have room for an nvidia chip in the 13" model.
We should see new MBP's before February at the latest, following Apple's schedule of updating their computers every 7-9 months or so. They won't have them ready before the November/Holiday rush, so I'd expect them in January or so.
